Cells are amazing
Cells are amazing! First the genome, then the proteome, epigenome/methylome, and spliceosome, now the transcriptome.
Recent years have seen error-correcting codes going forward and backward (and overlapping), codes based on 3D-fold neighbor proximity, protein folds based on alternate codon timing variations, meta-codes, methylation codes, circular RNA newly discovered to code for proteins.... it seems that almost every day they're saying, "You know those parts of the cell that we said were junk? It turns out they have a crucial purpose."
What's next, DNA that sends electric signals back and forth during transcription regulation? Yes, that's today's headline. Apparently the Designer of this amazing system is also a super-talented Electrical Engineer.https://www.evolutionnews.org/2017/04/electric-dna-circular-rna-and-other-epigenetic-wonders/
